Now-a-days traffic jam has become a serious problem in our urban life. Traffic jam means crowded mass of people, vehicles etc that makes movement difficult or impossible. We are familiar with it because everyday we are victimized by this problem. There are some reasons for this bothersome problem. Day by day the cities are becoming over-populated. The number of vehicles is also increasing vying with rapid growth of population. The loading or unloading of goods from trucks during day time, illegal markets by the roadside, unwise parking of vehicles, public meetings and processions are responsible for traffic jam. During religious festivals, i.e. Eid, Durga Puja traffic jam occurs near super markets, bus terminals and launch ghats. But according to the specialists the major reason is the lack of knowledge about traffic rules. The rickshaw pullers do not follow the traffic rules. Instead of following a queue, they overtake and create traffic jam. It causes a great loss of our valuable time and energy. Sometimes it becomes a matter of great sorrow when a patient dies for not reaching hospital or a student can’t appear in his examination because of traffic jam. Following traffic rules, introducing one way road, removing unlicensed vehicles etc. can solve this problem. Our govt. should take steps to solve this problem immediately so that we can reach our destination safely and comfortably.
Air is an important element of environment. We need air to breathe. We get oxygen from air. So we can not live without air. But air is polluted by smoke. Man makes fire to cook food, make bricks, melt tar for road construction and to do many other things. Fires create smoke and pollute the air. Railway engines and powerhouses create smoke by burning coal and oil. Mills and factories also belch a lot of smoke. Buses, trucks and cars use petrol and diesel oil. These too emit smoke. All these kinds of smoke pollute the air. Air pollution is harmful for our life. It causes different kinds of diseases such as pneumonia, bronchitis and other respiratory diseases. We should prevent air pollution to ensure a healthy and happy life.
